re:
But: Is there a reason OpenCPN only seems to accepts certain letter combination for the first two letters after the dollar sign?

Actually, OCPN does not care (or shouldn't care) about the "talker" ID. Could be anything.

The main core (not Dashboard) recognizes and processes the following messages, without regard to talker:

RMC, HDT, HDG, HDM, VTG, GSV, GGA, GLL

Are you having specific trouble with this? Any example sentences or configurations that don't work?

Thanks

Hello testers..

For the iENC, we need to select a single keystroke to return to ENC Standard display mode.

I propose the key "n". As in "staNdard", or even "Normal".

Anyone see any problem with this? Think about Plugins, alternate platforms (Mac, rPi, etc.).

Thanks
Dave

In the spam bucket. Got the VDR now, thanks.

I'll study now...

OK, according to NMEA0183 formally, we should not attempt to decode a sentence that begins with $P.....

This is meant to be proprietary, and not part of the standard.

c.f.
Standard NMEA-0183 sentences description

So, your $PFGLL sentences are ignored.

Of course we could fix this for your sentences. But what else will break? This is a large regression risk, since we have no idea what sentences that OCPN is really seeing in the wild. Makes me nervous.

Is there no way to redefine the TALKER for your interface? Seems to me that PFGLL is a good sentence, just needs to start with some character other than "P".

I got the KAPs, identified the trouble. These charts were mistakenly being interpreted as vector overlay charts (???) due to their specific names. Bad code, that was. Fixed now.

Looks like a nice place to anchor and swim. Got any pictures for the website photo Gallery?

Thanks

Dave, understood!

The TALKER is CANBOAT, https://github.com/canboat/canboat

Canboat creates the talker ID from a NMEA-2000 src ID, my N2K GPS has source "245" or 0xf5. Canboat represents 0xF5 by two letters, not using numbers, A..P with A representing a zero, and P representing a F. So I lucked out since my GPS gets the src ID 0xF5 and Canboat makes a "PF" out of it.

I will go back to the developer(s) of Canboat and ask to avoid an initial "P" during the creation of the talker ID.

Thanks again

What concept/feature is this? Any pointers?

Information, definitions and example cells for S-57 overlay cells here:
https://www.nauticalcharts.noaa.gov/..._overlays.html
and here:
bathymetric Inland ENC Product Specification | ienc.openecdis.org

Interesting feature especially for ad-hoc or crowdsourced bathymetry

The example gets recognized and accordingly placed by OpenCPN, but rendering is obviously not prepared for the overlay cells.

S57 overlay cells are commonly encountered in Euro Inland chart sets. They look like standard S57 cells, with a particular file name format.

In S57, the third character of the filename is used to decode the intended usage of the cell.

Example: /ENC_ROOT/US1AK90M/US1AK90M.000
This is an overview chart ('1').

/ENC_ROOT/US5AK7QM/US5AK7QM.000
This is a harbor chart ('5')

In Euro Inland, overlay charts are indicated by 'L' or 'A' in the third character.
iENC_AUSTRIA_ED9/ENC_ROOT/1SAD1870.000

These cells usually contain things like canal signs and other items not critical to normal navigation. OCPN renders them properly if found during chart loading.

For the bathy overlays in LongBeach, NOAA/USACE seems to be using also 'B' in the third character. I'll have to read the spec. to see about this, and teach O how to handle it.

FYI

[.Paul.]

The USACE issues the US Inland Buoys overlay named

3UABUOYS.000

which shows the USCG maintained buoy positions on top of the IENC's published by the Corps.

USACE also issues an overlay of soundings named

3UASW000.000

for the Southwest Pass of the Mississippi River. It overlays NOAA's ENC of the SW pass.

I just made a Pull Request which adds these two overlays to the chart downloader plugin in OpenCPN-master on GitHub. These overlays are updated every week or so.
